Add some user-friendliness to the warnings:

- Add OBJTOOL_ARGS="--verbose" option for making it easier to debug
  objtool warnings over email

- Remove per-file rate limiting (doesn't make sense for vmlinux.o)

- Add "missing __noreturn" warning

Josh Poimboeuf (5):
  objtool: Add '--verbose' option for disassembling affected functions
  objtool: Combine '--backtrace' with '--verbose'
  objtool: Remove superfluous dead_end_function() check
  objtool: Add per-function rate limiting for unreachable warnings
  objtool: Add "missing __noreturn" warning
